Combine all the ingredients except the chicken breasts in a blender or immersion blender container. Blend until the marinade is smooth and thick like dressing. Pour the marinade over the chicken breasts in a large zip lock bag and refrigerate for 4 hours. Remove the chicken from the refrigerator 30 minutes before grilling. Discard the marinate and grill the chicken on medium heat until cooked through. Allow the chicken to rest for about 30 minutes before serving.
Serve with your favorite toppings or dressing.
